January 22,1924.

Inzthe aforesaid recorder means are pro-` vided for taking a start and finish record from a time-controlled wheel after which the wheel is reset to: Zero by the operator. The advance `of the ,wheel from zero is controlled by means of 'a magnet whichin turn.

is time-controlled. In using this recorder there is the possibility .that the time-control-y led wheel will be stepped forward .after-'resetting but before the taking of a new start record. Under these conditions' an improper start record will be secured.

'One object of the present invention is .to provide means whereby the time-controlled wheel will' be locked against advancing movement afterresetting until after the succeedingstart recordfhas been taken.

Other objects of the .present invention reside in the improvement of ycertain details of construction. which will lbe more lfully vset forth'in the accompanying speciiication g and claims and'shown in the drawings which'di'sclose .a 'preferred embodiment of the invention.

In the drawingslis a side view of the recorder.

1n more detail, the recorder. comprises a suitable casing within which arerotatably mounted :time and time value wheels 10,11.A Fixed :to these wheels is aligning' wheel 12 andv a ratchetwheel 13. :The 'escapement wheel 14 at its `hub is free from ratchet wheel 13 and is .controlled bythe escapement v16 which in turn is `controlled Lby 'magnet'l` The escapement wheel has pivotedv thereonv a pawl 18 which cooperates with the ratchet wheel 13 and is engagedtherewith by means of a spring 20.' The time wheels and'ratchet and aligning wheel are .normally advanced by a coil" springfl. Thereset shaft 121', is fastto wheels 10 'and 11 and toratchet wheel 1923. Serial No. 652,696.

When the recorder is beingre` stored to zero .the operatoiwappliesthe `resettingzwrench22 to the end of the shaft21 andturns the .shaft Aand parts 12, 10.11 and 13 connected'therewith inza clockwise direc tion 'until pin 23 engages thenotch inndogf 2li which then snaps forwardunder the` lower ledge, of the pin 23.. During. .this resetting operation thepawl 18 cliclrsidly overtheteeth of ratchet wheel13. Theesf capement wheel ltremains stationarydurf ingfthis operation and thecoil spring lzis woundfup. At the time when .tbe.dog..24l hasengaged under the lower edge of lthe :pin 23the pawl 13 will'be `disposed halfewaylbetweentwo ratchet `teeth on wheel 13. If now the dog .24 be rocked anticlockwise, to the position shown in F ig. .3, the ratchet wheel v13 and the partsfconnected .therewith will automaticallymake one half a lstepof advance under vthe influence of the coil spring 15. Such movement willnot occur, however, until the dog 2a is retracted :rearwar-dly. This retraction of the dog is efffected'by the taking ofthe start record lin the following manner. The depression of manual 22 through hook 33 effects the oper-A ation .of the printing hammer 28aV in the usual manner. VPivotally connected to the frame which is rocked by the manual is .a li'nl; 23 which is slottedrat its end as shown'at 29 `to receive a pin v3() which is spring-con'- nected by spring 31 to the .endaofthelinlr 23.A Upon 4the actuation-of the printing. manual springl 31 will draw AforwardQon the pin30, which pin is carried in the bail frame 27 thereby rocking the ba-il in a4 counterclockwise direction and engaging :the aligning dog 32 with the aligning wheel 12. The upward rocking of the bail 27 will cause the 'tail' 26 of the dog` 24 to be elevated thereby rocking the dog anticlockwise and releasv ing the Zero stop pin 23. The Zero stop pin now moves forward to the position shown in F ig. 3. Also pivotally mounted on shaft is a card abutment lever This card abutment lever 33 is provided with a cam surface 34- which also is adaptcl to engage the edge of pin 23. il] ith the parts in the starting position as shown in 1, and also in the position shown in 3, this card abutment is in the full line position. After the stop pin 23 has moved forwaro to the dotted line position 23a 3) the card abutment lever will be rocked to the dotted line position and change the elevation of the card stop. The' card abutment lever 33 is also provided with a rearwardly cX- tending portion 35 which coacts with an interlocking element 36 which is adapted to be disposed in the path of the stop pin 37 on the hook member 38 as shown in Fig. 4C. This part of the mechanism is similar to that shown in the application previously referred to and serves to prevent further painting operations after the finished record has been taken.

.lt will be understood that after pin 23 leaves the notch in the locking dog 24 this dog will be restored to its engaging position by means of a suitable restoring spring 39 which is connected to the tail 2G of the dog and to pin 30.

In order to print on the record card a number identifying the machine a slug 4:0 is provided which is fixed to a suitably fixed arm i1 and disposed adjacent the print-ing point on the type wheels 10 and 11. The interlocking mechanism herein described is particularly adapted for recorders of this class wherein an indeterminate time may elapse between the resetting` of the wheels to zero and the taking of the new start record. Irrespective of the duration of this time the recorder wheels will be prevented from advancing until after the proper zero or start record has been taken. After such start record has been taken the various time wheels are advanced step by step by the coil spring 15 under the control of the escapement wheel 14. The ratchet wheel 13 through pawl 18 tends to drive the escapement wheel forward. Such movement is restrained by the scape arms 1G and leach time these scape arms are operated by the magnet 17 the time wheels advance one step.

ln order to provide for the replacement of different time intervals or value bands 10 or 11 I preferably provide the time wheels with brass bands L2 on their periphery having struck-up figures resenting the type. These bands are removable from the wheels by means of a clamping bloc-lr i3 shown in Fig. 1 and secured in clamping position by means of a screw 4:4.

Bef-'ore an initial record is made it is presumed that the recorder has been reset by rotating member 21. The opera-tor places a card in the card receiver and depresses the handle 22. The hammer 23a is operated to print a starting time record upon the inserted card. Depression of the printing handle 22 also releases dog 24 and releases the Zero stop pin 23. Type wheels 10, 11 then move forward under the cont-rol of the magnet 17. As soon as these type wheels move forward a card abutment lever 33 rocks to the dotted line position (Fig. 3) so as to position a different portion of the record card at the printing point upon the next recording operation. Upon the following recording operation the card is reinserted in the card chute and the handle 22 is again actuated. This operation prints the finish time record showing the direct elapsed time upon the record card. After the finish record is taken an interlocking element 36 comes into operation to prevent further printing operations after the finish record has been taken. Following the taking of the finish or elapsed time record, the type wheels and pertinent parts must be reset by a manual rotation of member 21. lWhen the type wheel is fully reset pin 23 will engage the notch in dog 24 which will snap forward under it. This dog will then prevent the advance of the type wheels until the taking of a new start record.
